The formarion of (γ+γ') eutectic and the control of σ-phase precipitation have been discussed. During solidification of the alloy, the dendritic segregation of Al and V is almost unespied, and of Ti, Cr and Mo is positive, especially, Ti being the most serious. This may impel the formation of segregation zone at eutectic reaction and the enrichment with σ- phase forming elements, e.g. Cr, Mo and Co, in the remainder liquid. Thus the increasing of σ-phase transformation may be tended. However, the σ-phase may be avoided either by adjusting the ratio Al/Ti taking the advantage of the difference of the segregation behaviour of Al and Ti, or by controlling the cooling rate after casting. 收稿日期: 1986-02-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 朱耀宵 徐乐英 赵洪恩 佟英杰 师昌绪 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I2/5 1 金柱,马实基,金属学报,10 (1974) ,12． 2 Mihalisin, J.R.; Bieber, C.G.; Grant, R.T., Trans.
